[0001] The utility model relates to the technical field of biomass combustion furnaces, in particular to an ash discharge structure used for biomass combustion furnaces. Background Art
[0002] Biomass refers to organic matter accumulated during the growth of organisms, including plants, animals and their metabolites. As a renewable energy source, biomass has a wide range of uses and important economic significance.
[0003] A biomass furnace is a device designed to burn biomass as a fuel, usually for heating, power generation or heat supply in industrial production processes. These furnaces are usually designed to use wood chips, wood fragments, straw, etc. as fuel, so they are different in design and operation from traditional coal or natural gas burning furnaces.
[0004] A large amount of ash will be produced when the biomass combustion furnace burns biomass. The biomass combustion furnace can automatically discharge ash according to the operation status of the combustion furnace and the degree of ash accumulation by introducing an automatic ash discharge system. However, the discharged ash may contain incompletely burned biomass residues and other impurities. If it is discharged directly, it will cause environmental pollution and waste of resources, and increase production costs. Utility Model Content

[0012] Preferably, one side of the processing box is rotatably connected to a protective door via a hinge, and a perspective window is provided on one side of the protective door.
[0013] Compared with the prior art, the utility model has the following beneficial effects: the first filtration is performed through the first screening plate, and then the dust continues to flow down to the second screening plate for the second filtration, and then the dust falls into the holding box again, and is filtered again through the third screening plate in the holding box, and then after multiple filtration and screening, the incompletely burned biomass residues and other impurities in the ash can be screened out more finely, which is beneficial for subsequent staff to recycle useful fuel, while reducing pollution to the environment and saving production costs;
